RHEL 7.3 - /proc/cpuinfo shows up to 2 Physical CPUs

Hi,

I getting this problem when checking the number of physical sockets on RHEL 7.3

My server has 4 Physical Sockets/CPUs, but when checking /proc/cpuinfo (cat /proc/cpuinfo | grep "physical id" | sort -u | wc -l), show up only 2 physical ids. Dmidecode -t4 it show that I have 4 Physical Sockets/CPUs.

Is there a restriction by RHEL to use only up to 2 Physical Sockets/CPUs??

Thanks
